The World Record of ‘largest Collection of books signed by authors’ has been achieved by Mr. Richard Warren from Lake Forest, California, USA.

Mr. Warren has a collection of Two Thousand Three Hundred Eighty One (2381) books all signed by their original authors. Mr. Warren started building his personal library in 1970 at the age of 16. Over the years he travelled and spoke around the world asking authors to autograph their books for him. Afterwards many other authors began to send him their books autographed.
